The ability to hack your shifters and change their gears is only one vulnerability class though.
If you could receive an instantaneous signal exactly as your rivals changed gears, it could allow you to anticipate and cover their attacks ("Everybody on the rival team just shifted up, get ready!"). Or infer when they're getting tired. This read-only vulnerability already exists with wireless speedometers, power meters, cadence sensors, heart rate monitors etc. - spying but not interfering.
With all those devices x 180 riders in close quarters, the RF environment inside a pro peleton has got to be wild. I'm amazed there aren't more problems from straight signal interference.
- SkyPuncher 2y agoYou don’t have to hack that. The sound of chains shifting is both audible and visual. There’s a pretty distinctive smacking sound that happens when chains find their new home. Particularly, on downshifts when the move to a small physical gear ring results in a brief reduction of tension before it snaps back to tension.
